Abstract
Systems and methods are disclosed that promote communication in an I2C Bus. These systems and methods include establishing a connection between at least two units within coupled together in a I2C bus, transmitting a message from a master to a slave, transitioning the slave to below a threshold during communications, and delaying additional messages from the master to the slave.
Claims21
A method, comprising:
- establishing a connection between at least two units within coupled together in a I2C bus, wherein each of the at least two units is a I2C communication unit, and wherein one of the at least two units is a master and one of the at least two units is a slave;
- transmitting a message from the master to the slave;
- transitioning the slave clock to below a threshold during communications;
- and
- preventing additional messages from being transmitted from the master to the slave.
2 more elements
A communications system, comprising:
- a master unit, wherein the master comprises a master clock signal generator that creates a master clock signal;
- a slave unit, wherein the slave comprises a slave clock signal generator that creates a slave clock signal, wherein the slave clock signal transitions from a high state to a low state during communications, and wherein the slave clock signal transitions from a low state to a high state upon completion of communications.
A communications system, comprising:
- at least two I2C communication units;
- and
- a connector, wherein the connector creates a connection between at least two I2C communication units, wherein the connector maintains a low clock signal between the clocks of the at least two I2C communication units during communication.
A system, comprising:
- at least two groups, wherein each of the two groups comprise at least one I2C communication units, and wherein each of the I2C communication units within a group are coupled together;
- and
- a connector, wherein the connector creates a connection between at least two groups of units, wherein the connector maintains a low clock signal between the clocks of the at least two I2C communication units during communication.
